2- ClaimS. (01.22.6-129?) The present invention relates to a nozzle forfilling the water tanksQf'raiIWay passenger cars.

Standard .railroad practice involves hoses attached to water hydrants atstations and car service yards, said, hoses being left lying on theground alongside the tracks when not in use. The end of each hose isprovided with a nozzle adapted for temporary connection with the-fillingspouts. of the. .car tanks- One object of the present invention is toprovide an improved nozzle which can be easily and quickly connected to,and detached from, the various types of car filling spouts in currentuse.

Other objects are to provide a nozzle that will remain clean and freefrom dirt, which will have long life, and which has only one partsubject to wear, which can be easily renewed.

Still further objects and advantages of the invention will be apparentfrom the following description, which should be read with theunderstanding that changes, within the scope of the claims heretoappended, may be made in the form, construction and arrangement of theseveral parts, without departing from the spirit of the invention, asdefined in said claims.

Reference will be made to the accompanying drawings, wherein Fig. 1 is apart sectional elevation showing a filling hose equipped with myimproved nozzle connected with a standard filling spout of a car havingoverhead water tanks.

Fig. 2 is a part sectional elevation of the same connected with onestandard type of filling spout of a car having under-floor tanks.

Fig. 3 is a part sectional elevation of the same connected with anotherstandard type of filling spout for under-floor tanks.

Fig. 4 is a longitudinal section, enlarged, of my improved nozzle.

Fig. 5 is an elevation of the end of the filling hose with my nozzlethereon, as it appears when lying on the ground.

In the drawings, the reference numeral 6 designates a portion of arailroad car having a water tank. In Fig. 1 the tank, not shown, isoverhead, or high up in the car or on the roof, and is filled through apipe 1, the lower end of which is attached to the frame of the car nearthe side by means of an elbow fitting 8, and which has a downwardlyextended filling spout 9 provided with a tapered outer surface.

In Fig. 2, the water tank is shown at In under the floor of the car, andis filled through a pipe ll terminating in a box-like filling spout [2secured beneath the floor near one side of the car,

and said spout 12' has an aperture l'3 in its outer wall. A suitableclosure, not shown, is understood to be provided for the aperture l3;

.otthose in currentuseon railroad-passenger cars.

A portion of a flexible hose is shown at I5, said I hose being attachedto a water supply hydrant, not

shown, in proximity to the track at a station or car service yard. Theouter end of the hose [5 has a shut-off valve I6, from which extends ashort nipple ll of rigid pipe. A circular guard plate 18 is secured tothe nipple I! to prevent the latter from coming in contact with theground when the end of the hose is dropped, as shown in Fig. 5.

So much is standard equipment in current use. A short length of flexiblehose, not shown, is commonly slipped over the end of the nipple I1, andleft thereon, to connect it with the filling spout 9. Such short lengthof hose, being flexible, bends down and frequently becomes dirty byontact with the ground, and such dirt is washed into the car tank andcontaminates the water therein.

My improved nozzle comprises a rigid tubular fitting l9 having aninterior thread 20 at one end, and tapering outwardly to a largerdiameter at its other or outer end. The threaded end 20 is screwed onthe nipple H. The larger outer end of the fitting I9 is provided with anannular interior groove 21 in which is seated a rubberv gasket 22 ofL-shaped cross section, as shown in Fig, 4. The interior diameter of thegasket 22 is such as to enable it to fit snugly around the filing spout9 of the overhead tank, as shown in Fig. l, and to maintain therewith ajoint tight enough to stand the pressure necessary to raise the waterinto the overhead tank.

The outside diameter of the fitting l9 enables it to be inserted throughthe aperture 13 of the filling spout 12 of the under-floor tank shown inFig. 2. However, when a filling spout is encountered which has a smallaperture, as shown at It in Fig. 3, a short nipple of rigid pipe 23 isinserted in the end of said fitting l9 and frictionally held by thegasket 22, as shown in Figs. 3 and 5. This rigid nipple 23 is smallenough in diameter to pass through the aperture 14.

It will be seen that my improved nozzle, whether the fitting I9 be usedalone or with the additional nipple 23, is a rigid structure, rigidlyconnected with the pipe nipple l1 and shut-ofi valve l6, so that allparts of it are held in the air by the guard disk l8, and no part canbend down into contact with the ground to be soiled thereby. Connectingthe nozzle to or disconnecting it from any of the standard fillingspouts shown is a simple and instantaneous operation, consisting ofmerely pushing it on or pulling it vofi the spout 9 of Fig. 1, orinserting it into or pulling it out of the filling apertures 13 or l4 ofFigs. 2 or 3.

The fitting I9 is permanently attached to the pipe nipple I1, and beingmetal, lasts indefinitely. The only part subject to wear is the rubbergasket 22, which can be quickly replaced when worn.

I claim:

1. Means for filling railroad car water tanks comprising a water supplyhose, a valve fitting at the free end. thereof, a rigid pipe nippleextending from said valve, a rigid tubular nozzle having one endthreaded upon said nipple, the axes of said nipple and said nozzleextending in a straight line, a flexible annular gasket mounted withinthe other end of said nozzle, and a substantialy circular rigid guardsurrounding and secured to said nipple in a plane at right angles to theaxis thereof, said guard being so positioned lengthwise of said nipplethat the weight on the valve side of said guard exceeds the weight onthe nozzle side thereof.

2. Means for filling railroad car water tanks comprising a water supplyhose, a manually operated valve having a handle at the free end of saidhose, a rigid tubular nozzle having one end connected with said valve,the axes of said valve and said nozzle extending in a straight line, aflexible annular gasket mounted within the other end of said nozzle, asubstantially circular rigid guard mounted between said nozzle and saidvalve in a plane at right angles to the axes thereof, the

radial distance from the line of said axes to the REFERENCES CITED Thefollowing references are of record in the file of this patent:
